"An adaptable, lightweight, and compact water filter, the Sawyer Mini is a useful personal water treatment system that is very inexpensive. It can be used as a straw or inline in a water reservoir, making it more useful than other straw-style filters. Weighing only 1.4 ounces and costing around $25, this filter easily takes our Best Buy award."
